I PUMP Filed Feb. 21. 192v 2 Shets-Sheet 2 'ATTORNEY to the pump cylinder 1 andopens into the latter through the cap 2.

The valve mechanism 30, as shown best in Fi ures 3 4 and 5 com rises a housin in b 3 7 b whicha tapered, plug is revolubly fitted and which is held tightly to its seat by means i of a spring 36 that bears against the end of i the housing and against a nut '37 threaded intoa coaxialstem 38 projecting from the smaller end of the plug. The valve housing is provided, at oneside,'with a tappedopening 39 for receiving the 'pipe 29 and at a point diametrically opposite the opening 39.;

is provided withachannel 40 that leads lati erallyand into an opening41with which the pipe 31' connects. The plug-35 isprovided -wi-tli"a transverse port 'al which, by 'certain ositioni-n i of the lu as shown in Fi ures i v I: b

This is tapped into a port 71 located in the side of the valve housing in the plane of the plug channel44. There is also provided a small port 75 in the plug connectingv with channel 44 and adapted to provide a connection be tween pipe 29 and pipe 70 when the plug is turned 'toa position to cut off air pressure to the pump cylinder. A valve cook 78 is provided in pipe 70 for controlling the rate or amount of flow of air to the tank 11 and a back-check 79 is providedto prevent back flow., "Electric circuit for the motor isdelivered thereto underthe control of a switch meCh'anismSO andithis is of thatcharacter adapted to 'be operated between fon and ofi? positions by a control device 81 actuated by air pressure delivered thereto through-a connection 82withpipe70 so that the apparatus will act automaticallyto start when the waterpressure falls below a certain amount and to stop when a certain predetermmed pressure 1s reached.

.An outlet pipe 85 leads trom the lower end ofthe tank 11 and this mayextend to a point where'the water is toibe' used and would there bev'equipped with a faucet 86 With the deviceiso'constr ucted, its operationwould be as follows:

With. the pumpcylinder lowered into a well sufficiently 'to be submerged by the water,and withtheficylinder connected by voir .11 andithe pipe'31 connected through v the valve mechanism 30 with the air storage reservoir 26 and compressor 15', the motor 161s startedfto iinalntaln the air pressure I thepipe 10with the top of the-storage reserand'ito drive theftiming gear 51 As the compressor operates itfbuilds up anair pressure within the tank. 26: and when'the valve 30' is opened this air pressure 'is admitted throughthe pipe 31finto the top of the cylinder 1' so'aslto force the water from the cylinder through the pipes 9 and 10 into the tank-[11. Y'Therate of-rotation of the gear 151 is so'timed that the plate5O will contact i withthe lever 49 at aboutthe time the cylinder lis emptied of water; and the valve plug will be'frotated to a positionat which the the channel-4L0 in the valve and the'pipe 31 will be: connected withatmosphere through compressed airsupplywill becut off from' the plug channel 'li5and valve opening 46. c,

This permits 'the' aiiywithin thecylinder l-to escape-to atmosphere and'the'cylinder to fill With water; I At about the timethe cylinder 1 againfilled the pla e 59 on-the timing gear 51 again contacts with" thefvalve lever and l actuates the waive to again connect pipe 31' rwith air supply and to shut off the opening to atmosphereesou that the "compressed 2' air be delivered fto'thecylinderl; and the 9 andl O to the storage tank 11,, This opera- ;tionr'eont'inues until sufficient Water has been delivered tothestorage tank 11 that the air pressure] is built up sufficiently to actuate :the control mechanism 81 to close the switch '80 and thereby stop the motor. I 1 The Whole system is rendered automatic by the following means: When it is desired; to -udraw ofi a1 supply of Water from the tank 1 11,;the faucet-86 is opened. As the Water lovv-ersjin the" tank 'll'the air pressure is rep .du'cedand this, through theconnecting pipes e 7O and'82 Withthe control mechanism 81,

sfopens' the switchBO andstarts the motor 16 which drives the compressor to build up an air pressure in the tank26 and this pressure r .isintermittently delivered to thepump cyl- 3 Qinde'r, through pipes 27,29 and BL'tO BXPeI Top era-tion.
